Exploitable marketplaces just seem to be seesawing back and forth between those closing exploits and those finding new ones. Anything that gets massive these days seems to get into this stage because of the profit incentive on both sides. I wonder if there's data on whether the general "arc of progress" is going in the right direction? I go back and forth depending on the day.

Personally I've just established my own rules of the road to avoid the bad side, like deleting Facebook and all social other than Twitter, using browser extensions in Twitter to filter out trending stuff, and being very careful and methodical about purchasing from Amazon including avoiding almost everything isn't a reputable company that I can do a simple background check on. I've even been fooled here but it's generally pretty easy to figure out.
